Cause of Defects
- Lack of provision or failure of a waterproofing membrane around the pipe may lead the water leakage through the structural floor (Figure 1).
- Aging of the waterproofing membrane could lead to failure of water-tightness of the discontinuity at the penetration.
- Porous infill of the cold joint at the penetration attributes by the hacking of concrete slab and/or leaving large openings during casting could be another factor.
